Inventor: BENJAMIN CHARLES
IPC: G07F11/24
Filed: 1968-11-28
Abstract: 1,260,478. Shoots. AUTONUMIS Ltd. 27 Nov., 1969 [28 Nov., 1968], No. 56503/68. Heading B8S. [Also in Division G4] Articles 3 in a magazine 2 are discharged one by one by finger 11 carried by block 10, the block being pivoted at 12 to disc 4 which is oscillated. Disc 4 is provided with two faces 8 and 9 so that on the forward anti-clockwise movement of disc 4 block 10 engages face 9 and moves forward to discharge the bottom article 3, the block 10 engaging stop 16 at the end of its movement. Disc 4 then reverses and block 10 as it moves rightward pivots anticlockwise about its pin 12 till it engages face 8 which thus moves the block rightwards in a lower position to avoid engagement with an article 3. The cycle then starts again. The disc 4 is connected to an operating or release mechanism of a vending machine.

Abstract: 1341086 Friction clutches DAIMLER-BENZ AG 8 Dec 1971 [19 Dec 1970] 57062/71 Heading F2C In a friction clutch for a motor vehicle wherein two driven discs 10, 11 are normally clamped between a flywheel, intermediate plate 12 and a presser plate 13 by a diaphragm spring 14 and the intermediate plate 12 is moved away from the flywheel during clutch disengagement by tangential spring strips connecting the intermediate plate 12 to a clutch cover 16, axial separation of the intermediate plate 12 and flywheel is limited by abutments 23, 24 fast with pins 20 frictionally engaging bores in the clutch cover 16 and the position of the pins 20 is automatically adjusted to take up wear. The pins 20 are held in bores in the clutch cover 16 by clamping sleeves 22. The pins 20 carry abutments 23, 24 separated by a spacing sleeve 25 to permit the normal clutch disengaging movement of the intermediate plate 12. The friction connection between the pins 20 and clutch cover 16 is such that it permits the intermediate plate 12 to act through the abutment 23 to move the pins 20 left relative to the clutch cover 16 to take up wear during clutch engagement but prevents rightward movement of the pins 20 when the intermediate plate 12 engages the abutment 24 under the action of the tangential spring strips.

Preferably the ratio of the heat capacity of particles (a) to the heat capacity of particles (b) is greater than 50 and less than 1000. The difference in heat capacities is effected either by using different resins for the outer layer and core, or by using the same resin throughout, the particles (a) being in this case larger than the particles (b). Examples are described involving polystyrene, polyethylene, polypropylene, polyvinylchloride, methacrylic resin, acrylonitrilebutadiene - styrene copolymer, acrylonitrile - styrene copolymer and polycarbonate resins. Blowing agents mentioned are dinitropentamethylene tetramine, dimethyldinitrosoterephthalazide, benzene sulphonyl hydrazide, toluenesulphonylhydrazide, azobisisobutyronitrile, diazoaminobenzene, trihydrazinetriazine, paratoluenesulphonylsemicarbazide, oxybisbenzenesulphonylsemicarbazide and azodicarbonamide.

Title: Process for the preparation of carbon black
IPC: C09C1/50
Filed: 1968-12-24
Abstract: 1,244,879. Carbon black. PHILLIPS PETROLEUM CO. 24 Dec., 1968 [29 Dec., 1967], No. 61364/68. Heading C1A. Carbon black is produced by a process comprising contacting a hydrocarbon reactant with a primary free oxygen-containing gas under carbon-black-producing conditions in an upstream region of a reaction zone, passing the reactant mixture downstream through the zone, quenching the mixture at the downstream end of the zone and recovering carbon black from the effluent from the zone, wherein a secondary free-oxygen containing gas is introduced into the zone downstream from the region in which the conversion of the reactant into carbon black is substantially complete but upstream from the point of quenching. The secondary gas is introduced in an amount sufficient to reduce the time required for detarring the carbon black to a tar-free carbon black having a photelometer value of at least 80. The primary gas is a hot combustion mixture produced by burning a fuel in the presence of an amount of oxygen in excess of that required for complete combustion of the fuel. The secondary gas is preferably air and is introduced in an amount of 2-50 volume per cent of the volume of primary gas. The secondary gas stream may also contain a vaporous fuel, the free oxygen in the secondary gas stream being less than that required to completely combust the fuel. The process can be carried out in known types of furnaces (see Figures not shown), with the reactant mixture passing axially through a generally cylindrical reaction zone. Preferably, the primary gas is formed as an annular gas stream flowing through the zone around an axial stream of hydrocarbon, the secondary gas being introduced tangentially. In another embodiment, some of the primary oxygen-containing gas is introduced tangentially into the upstream end where the hydrocarbon feed is introduced axially.

As shown in Fig.1, the motor unit B is itself detachably mounted on the camera, and comprises the actual motor and a control circuit, Fig.3 (not shown). The current source is a battery in a housing E which is also mounted on unit B by means of terminals 1. The control unit C is mounted on unit B by means of a connector ring 2, and a knob 3 on unit C operates a change-over switch which selects one of two circuits in the motor unit so that the camera operates to take either a single exposure or a continuous series of exposures. The shutter release 4 is also mounted in unit C. In the modification of Fig.4, the control unit C is not mounted directly on the motor unit B, but attached to it indirectly by means of a cable L. Thus the camera can be operated by remote control, the release 4 and knob 3 being on unit C at the remote end of cable L, where it is mounted for convenience on a hand grip N1.

Filed: 1978-10-18
Abstract: Making use of solid state technology and integrated circuits to control the stylus in an electronic stencil cutter using pulse modulated signals, the reflected light spot from the document to be copied is received by a silicon photocell 5 from which analogue signals pass to an amplifier 6 and interface circuit 7 and thence to a voltage to frequency converter 8, either directly for a "line" print or through a tone correcting circuit 9 for a "tone" print. The output from the converter 8 comprises pulses whose frequency is a function of the analogue voltage, and which pass to packages 10 comprising monostables, which shape each pulse to a form suitable for a centre-tapped transformer 12. V channel MOS power FET switches 11 are used to amplify the current supplied to the transformer, thereby enabling about 400 volts to be applied to the stylus which at each pulse cuts a dot in the stencil, not shown, which is mounted alongside said document, the tones to be printed depending on the density of the dots. The tone correcting circuit 9 comprises a summing network which provides a voltage output that varies in relation to the input so as substantially to eliminate inaccurate tonal variations in the reproduction. <IMAGE>
